Specification of Letters Patent.

Patented Mai'. 6, 1917.`

Original application filed August 15, 1914, Serial No. 856,991. Divided. and this application filed November To all whom t may concern.' v

Be it known that we, ALoYsiUs Josnrii KUSTERER, a citizen of the United States, re-

siding at Richmond, in the county of Henrico and State of Virginia, and CHARLES SANDERS, a citizen of the United States, residing at South Richmond, in the county of Chesterfield and State of Virginia, have invented certain new and useful Improvements in Feeding and Severing Mechanism; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I v

This invention is a division of application 856,991, filed August 15th, 1914-, and relates to feeding and severing mechanism for feeding and severing a sheet, as for instance ,a sheet of gummed paper to an automatic machine. 1

An object of the invention is to provide improved feeding and shearing mechanism for feeding a sheet of paper or other material to an automatic machine for producing boxes or other articles, and with improved means for shearing the sheet vor web into the necessary or required lengths or sections used in such automatic machine; Y x

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

rlFhe improved feeding and severing mechanism which forms the subject-matter of thisr divisional "application is Ashown in the vparent application as associated with abox shell making machine, but it is to be understood that the utility of the feeding and severing mechanism is not limited to the vspecific .machine to which it is there shown attached, nor to a machine for any specific orv special purpose, but is adapted to feed and sever a web of sheet materialfor any purpose for which such feeding land severdescribed in conjunction with the box shell making machine whichV forms the subjectmatter. o-f the parent application, it being understood thatits scope is not thereby limited to such association, or to a utility as forming part of such organized structure. As shown inthe drawings, a frame 30 is employed supported in any approved manner as by the legs 31. Upon this frame 30 a shaft 32 is journaled receiving power in any approved manner, as bythe gear 33, seen particularly at Fig. 3 from the shaft 34, which in turn receives power in any approved manner, as 'byA the pulley 35.

- Upon the shaft 32. a number of cams are employed, shown at 3G, 37 and 38. Journaled also upon the frame 30 is a rock shaft 39 upon which is fulcrumed a. lever 40, an arm 41 being rigidly connected therewith and oscillated thereby. r1`he arm 41 is provided with a pin 42, upon which is journaled a spool 43 carrying a web of paper or like material 44.

The paper web passes over a roller 45 journaled upon the shaft 39 and thence over any suitable pasting mechanism. After passing' the pasting mechanism, the web passesV over a roller 46 j ournaled upon a pivoted arm 47 which said arm 47 and roller 4G are oscillated by means of a link 48 connected with the lever 40. r1`he level' 40 is itself oscillated from the cam 38 by means of a walking beam 49 carrying a link 50 connected with the lever 40 and a. link 51 malring proper engagement with the cam 38 as shown more particularly at F ig. 5. At its end opposite the connect-ion with the link 50 the lever 40 is connected with the link 52 which is in turn pivoted to the block 53 slidable in the guides 54, a slot 50 being` provided in the lever 40 to vary the throw of such lever. Pivotally connected with the forward end of the block 53 are arms 55 and 5G carrying respectively jaws 57 and 58. The arms 55 and 55 and in conseruence the jaws 57 and 58 are constructed to move in unison by employing` gears 59 and 60, seen particularly at Figs. 5 and G, which said gears are concentric with the pivoting of such arms and being intergeared it is obvious that the jaws will move toward and away from each other simultaneously. rlhe jaws and arms are held yieldingly closedby means of a spring 61 and are opened in proper timed relation to the operation of the device by means. of the cam 37 carried upon the shaft 32 and a lever' G2 pivoted at 63 and engaging under a roller G4 carried by an arm G5 rigidly connected with the pivoting of one of thearms as 5G, and allas shown more particularly at Fig. (3. As then the lever 62 is raised by the cam 37 the jaws are opened irrespective of their position relative to the guides 54 and when the lever G2 is lowered the aws are closed by the spring 61. After passing over the roller 46 the web 44 passes between the jaws 57 and 58, as shown more particularly at Figs. 4 and 5. It is obvious, therefore, that with the opening and closing of the jaws 57 and 58 properly timed they will grasp or clamp the web 44 at the rearward extreme of their limit or at the lower point of movement, as shown at Fig. 4 and continuing to grasp such web will advance to the position shown at Fig. 4, carrying the web therewith. At such point of eX- treme forward or upward movement the jaws are properly opened by the lever 62 and the web severed by the shear members.

This shearing device comprises an upper shear blade (SG, and a lower shear blade 67. rEhe shear blade GG is carried by an arm 68, which is adj ustably connected with the block 69 provided with a rack 70 in engagement with a pinion 71. The shear blade 67 is carried by an arm 72 rigidly connected with a block 73 provided with a rack 74 also engaged by the pinion 71. As the blocks 69 and 73 are mounted slidably relative to each other it is obvious that as the pinion 71 is rotated the blocks and the shears carried thereby will move in opposite directions. To rotate the pinion 71 a shaft 75 is rigidly connected therewith and carries a second pinion 7 G engaged by a rack 77 which engages and is operated by the cam 3G, as shown more particularly at Fig. 10.

The shears are adjusted for proper cutting by adjusting the shear 66 carried upon the arm (38. The proximity of the arm G8 to the arm 72 is controlled by means of a screw 78 while angular adjustment is accomplished by means of screws 79 and 80 and clamped to position by screws 81 and 82, all of which will be perfectly apparent by an examination of Figs. 8 and 9.

To enable the jaws 57 and 58 to properly grasp a web of paper made slippery by the application of paste thereto one of the jaws, as 57, is provided with lugs 83 having concavities therein as shown more particularly at Fig. 13, While the other jaw, as 58, carries screws 84 having rounded extremities to fit in the concavities as shown in the same iigure. To prevent the pasted paper from adhering to the jaws 57 and 58, or to the shears 6G and 67 stripping wires are employed, wires 85 being under the web and attached to the frame as shown at Fig. 4 while the wires 86 are above the web as shown at Figs. 4 and 13, andare carried by arms 87. rilhe jaw is provided with recesses to receive the wires 85, as shown at Fig. 13, while the wires 8G are accommodated by reason of the jaw 57- having the lugs 83 which form a space between the jaw proper and the web.

To prevent the return of the web 44 after it has been severed by the shear blades (36 and 67 and with the return of the jaws 57 and 58 a detent 87'is employed, shown particularly at Fig. 14. This detent is mounted upon a shaft 88 upon which is also mounted a lever 89 having a weight 90 for holding the detent in grasping engagement with the web 44. It is desirable, of course, that the detent release the paper web upon its forward movement and for this purpose a lever 91 is mounted upon a shaft 92, which carries an `arm 93 bearing upon a cam 94'upon the shaft 32. The cam 94 is so arranged-that the lever 91 and the detent 87 are lifted at each advance movement of the web 44 and permitted to drop under the action of the weight 90 at each return movement of the jaws 57 and 58.

lio

In operation a spool of paper 43 is placed upon the spindle 42 and the web unwo-und from the spool, as shown at 44 to pass about the roller 45 and under the detent 87 and between the jaws 57 and 58. The rotation of the ,shaft 32 then causes the lever 40 to oscillate as hereinbefore described to reciprocate the jaws which are opened and closed in timed relation, as hereinbefore described to grasp the paper web when at the extreme lower limit of their movement and to remain in such grasping position until they reach the upper extreme of the movement passing between the shears 66 and G7 in such upward movement, as shown particularly at Fig. S. Reaching such upward limit the jaws then are opened in the manner hereinbefore described and pass backwardly, the shear members opening to permit such return. The shear members, it will be noted, are carried upon arms extending from one side of the web of paper while the jaw members are carried upon arms at the other side of the web of paper, so that either may open to permit the passage of the other between. The shears preferably do not act until after the jaws have been opened to release the web and the section of paper thus severed is taken up by any mechanism which is to use the same, the illustration showing a winding mandrel for winding such section of paper about a cardboard blank. It is to be understood, however, as hereinbefore stated, that the winding mechanism or any other mechanism has nothing to do with the present invention, the present invention extending only to the point of advancing the web and severing a section therefrom.

It is obvious also that asthe takeup roller 46 osoillates with the arm 40 the unwinding of the-web 44 from the spool 43 occurs while the web is being rigidly held by the detent S7 and that when the jaws are advancing to feed the section of paper forwardly the take-` up roller 46 also advances thereby permitting the easy movement of the web of paper.
